Aims and objectives: The failure of arterio-venous (AV) access increases morbidity and healthcare cost in patients with end stage renal disease. AV access failure may occur by thrombosis secondary to stenosis of the anastomosis/draining vein or of the graft. The stenosis is caused by neointimal hyperplasia, unfavorable [...]

Methods and materials: We retrospectively reviewed all the PTA performed in dysfunctional upper extremity dialysis access at our center in last 5 years. CDU records performed after the procedure and at 6, 12 and 24 weeks from the intervention were used to assess the functionality of the fistula. Peak systolic velocity and[...]

Results: A total of 421 PTA in 183 patients were reviewed. 160 procedures were excluded for missing data (CDU or DSA not performed or recorded) or because performed on lower extremity AV access. CB and SB angioplasty were performed respectively in 22 and 73 patients. Twenty patients had residual stenosis of [...]

Conclusion: CB provides better technical results compared to SB for the treatment of NF, but without affecting the functional outcome at short or long term.
